AGRICULTURAL BoiLER.

SPECIFICATIONl forming partbf Letters Patent No. 367,209, dated July 26, 1887.

Application filed January 24, 1887.

To @ZZ whom it may concern:

Be it known that we, JOHN JUST and PETER J UsT, both residents of Sauk City, in the county Sauk and State of Wisconson, have invented certain new and useful Improvements in Agricultural Boilers; and we do hereby declare that Fig. 3 is a perspective view of an upright form.

of our boiler, and Fig. 4 is a vertical sectional view of this form.

Similar numerals of reference indicate corre# sponding parts in `all the figures.

Our invention has relation to agricultural boilers used forthe purpose of steaming feed for animals, and for steaming, cooking, and

heating purposes generally; and it consists in v the improved construction and combination of parts of such aboiler, as hereinafter more fully described and claimed.

In the accompanying drawings, the numeral 1 indicates the outer shell of the boiler,which is shown cylindrical in the first two figures, and vto which we shall first have reference. Inside of this horizontal and cylindrical outer shell is eccentrically secured a fire-tube or furnace-tube, 2, and the ends of the outer cylinder and the inner ire-tube are secured upon two registering sets of flanges, 3 and 4, upon the forward and rear heads, 5 and 6, of the boiler.

The front head of the boileris provided with an aperture, formed inside of the eccentric flange, and this aperture is closed by means of a hinged fire-door, 8, having suitable draft-ap` erture, 9, and having a suitable latch, 10. The rear head of the boiler is`provided with a smokestack, 11, and a rod, 12, passes through both heads near their upper edges, andisprovided with nuts 13 for drawing the heads together.

A shield or defiector, 14, is supported inside of the boiler in the upper portion of thesame, having spaces formed-between its edges and Serial No. 225,315. (No model.)

y cutoff, the'steam used for the cooking or other purposes beingsupplied through this outletp The safety-valve pipe is provided at its upper end with ajoint, 18, the upper end of which forms a seat, 19, for the valve, while the end of a pipe, 20, having a cock, 21, is inserted into the horizontal branch of the joint, and is connected by means of a flexible tube, 22, to a joint, 23, inserted into the upper end of the feed-water barrel 24. This barrel or reservoir is placed slightly elevated over the boiler, and is provided with a filling-aperture, 25, in its top andwith cocks 26 and 27, near its top and bottom, the upper cock serving to test the water-level in the barrel when it is filled and the lower cock serving to draw off water from the barrel. 1

A feedpipe, 28, enters the barrel with its upper end and has its lower end secured in a T-joint, 29, in the bottom of the boiler, and the feed-pipe is provided with asuitable cock, 30, while the horizontal branch of the T-joint, opposite to the branch into which the feed-pipe enters, is provided with a blow-ofi' cock, 3l, through which the boiler maybe blown off.

The side of the boiler is provided with the usual'gage-cocks, 32, by means of which the water-level may be ascertained.

When the boiler is to be used, the barrel or reservoir islilled and water letinto the boiler through the feed-pipe, whereupon the fire is started, and when the water-level becomes low in the boiler the cock upon the steampipe extending from the safety-valve pipe is opened, as is also the cock upon the feed-pipe, when the water from the barrel will iow through the feed-pipe and into the boiler. The steam passing out through the outlet-pipe to its destination will be dry and free from water, as the shield or detlector covering the opening for t-he pipe in the top of the boiler will prevent water from passing into the pipe as it is agitated by boiling, thus rendering the steam more serviceable, and causing the boiler to be run with less water than a boiler in which the water is ICO liable to pass over with the steam. The heating-surface of the eceentrieallyarranged eylindrieul fire-tube is comparatively large for the boiler, and the space between the bottom of the tube and the shell of the boiler is very nar1ow,so that the water will be heated very quickly and steam will be quickly generated.

In Figs. 3 and 4 are shown views of a different form of the boiler, the boiler being shown vertical and with the smoke-steel: in the top. rlhe outlet-pipe is secured in the upper head or top of the boiler, andthe steam-supply pipe for the barrel or reservoir extends frein near the upper end of the boiler, while the feedpipe extends from the barrel or reservoir into the lower end of the boiler. The outlet-pipe is provided with a curved pan or shield under the end entering the top of the boiler, thesaid pan or shield serving the same purpose as the shield or defleetor in the horizontal boiler, and the functions of all the parts of the boiler are exactly the saine as of the horizont-al boiler.

Having thus described our invention7 we claim and desire to secure by Letters Patent of the United States* The combination, with a steam-boiler, of a pipe entering the top of the saine, and having a suitable stop-cook and provided with a safetyvztlve, an outlet-pipe entering the top of the boiler, und having a stop eoek or valve, a feed-water barrel or reservoir-supported above the boiler, and having :L pipe near its top oonneeted to the safety-valve pipe by u flexible tube, and having gage-cooks and a iilling-aperture, and a feed-pipe extending from the bottom ofthe barrel to the bottoni of the boiler, as and for the purpose shown and set forth.

In testimony that we claim the foregoing as our own we have hereunto affixed our signatures in presence of two witnesses.
